“Hey Steve, who’s the loud guy?”

Apparently you children have never seen "Fly Away Home", it was a fairly popular corny movie in the 90s. We had tons. This one featured not Jim Carrey from "Dumb & Dumber". Sorry you didn't get the memo.

Isnt there a movie from the 90s about this?

Fly Away Home (film, 1996)
https://en.wikipedia.org/wiki/Fly_Away_Home

Inspired by true events, Fly Away Home dramatizes the actual experiences of Bill Lishman who, in 1986, started training Canada geese to follow his ultralight aircraft, and succeeded in leading their migration in 1993 through his program "Operation Migration". The film is also based on the experience of Dr. William J. L. Sladen, a British-born zoologist and adventurer, who aided Lishman with the migration.

The birds: where's my aircraft? This is bullshit.

that is not a job, it is an assignment, the job is pilot

“Dear cranes, we know you have a lot of choices when it comes to air travel, so we just wanted to thank you for choosing to fly your damn self”

At first I thought that was a very lazy crane

So, clearly the plane runs out of fuel along the way. Do they have designated landing spots to refuel? Or does the pilot land at a regional airport? I suppose the birds would be okay landing at an airport, but do they then land at the airport every time during their migrations from then on? I'm guessing they might land somewhere more bird-friendly nearby, and gradually change the stopping points through the years.

Yeah there's this one job, but...

But what?

No, nothing. You wouldn't like it.

Come on, tell me!

How comfortable are you in animal's clothing?

..i'm in.

..but - you - I haven't..

Tell me where to go. Give me the deets.

I don't even - can you ..make loud sustained noises?

That's a long time to be dressed as a crane.

Or that the number cause of death on the job for wildlife biologist is aircraft related accidents.
